[ male announcer ] along with support, chantix (varenicline) is proven to help people quit smoking. it reduces the urge to smoke. chantix didn't have nicotine in it, and that was important to me. [ male announcer ] some people had changes in behavior, thinking or mood, hostility, agitation, depressed mood and suicidal thoughts or actions while taking or after stopping chantix. if you notice any of these, stop chantix and call your doctor right away. tell your doctor about any history of mental health problems, which could get worse while taking chantix. don't take chantix if you've had a serious allergic or skin reaction to it. if you develop these, stop chantix and see your doctor right away, as some could be life threatening. tell your doctor if you have a history of heart or blood vessel problems, or if you develop new or worse symptoms. get medical help right away if you have symptoms of a heart attack or stroke.
